DUKECAN2.zip is an edited version of dukecan.zip. The original is an unfinshed beta TC with 8 levels. Only 4 were finished. Level 1-Canadian Airlines, level 2-Holiday Inn, level 6-Downtown Toronto, and level 8-Sky Doom. The unfinished levels were removed from the .grp file in DUKECAN2 so you can play the finished levels only. Both versions are included in this zip file. Use the files in the dukecan folder for the original TC, OR use the files in in DUKECAN2 folder for the edited version.
